Can may Hen die from the poisonous frog

Hello my name is almost 6 year old and is not feeling well since 5 days now she's been drinking just a little bit she has stopped eating since two days before she was eating tiny tiny little bit anyway I saw a frog 6 days ago I don't know I think maybe it could have been poisonous I live in South Florida I don't know if she pecked him or not so if she is poisoned how long does it take to die from it. What would be the signs that she is poison what can I do

Do you know how long they can be sick for because my hand is 6 and 7 days and she has not eaten anything since 3 days he's just drinking very weak but still tries very hard to keep up with the others She lays most of the day
